Hard to say if there will be any worthy percipitaiton for Mormon Emmigrant trail next weekend... Couple of my co workers were up there on Thursday and said you have to go up fairly far(6000+ elev=13 mi at least) If you want to have good run then I suggest taking the time to go past Polock Pines and up Ice House Road to Wentworth Springs.

If you want more info let me know I would up for going next weekend
